This invention relates to no-tank flush valves for closetsand the like and has particular relation to such a valve mechanism which will deliver a plurality of quantities of water, selectively, to the closet.

During periods of drought and in cities where there is a limited water supply, the attention of the public works engineers has been directed to the necessity for the adoption of all necessary means to conserve the supply of water and prevent its waste and the amount needed and in some instances it is many times the required amount.

The primary object of this invention is the provision of an improved closet flushing device. I Another object of the invention is the provision of an improved olosetfiushing device capable of delivering any one of a plurality of amounts of water to the closet, under control of the operation.

Another and further object of the invention is the provision of a closet flushing device which has a single manually controlled means having connections to the water control means to deliver a predetermined amount of water to the closet when one movement characteristic is given to the manually controlled means and adiflferent predetermined amount of water to the closet when a different movementoharacteri'stic isgivento the manually controlled'means.

Another and still further object of theinvention is the provision of a closet flushing device which is provided with twovalves of the dashpot type and a selective control device for controlling the operation of these -valves. c

The numeral 10 designates the body of the device having an inlet opening 11 and an outlet opening 12. The inletopening 11 connects to an inlet chamber 13. The inlet chamber 13 has two openings 14. and 14 which i connect tothe outlet chamber 15 whichin turn connects to the outlet opening 12.

In the openings 14, 14 are located the flush control valves 15 and 15'. These valves 8 control the starting and stopping of the flushing operation. On one, side of the inlet chamber 13 and having one end exposedthereto are two cylinders 16, 16. In these cylinders 16, 16 are located pistons 17, 17 In order 4 to control themovement of the valves 15, 15

from the pistons l7,' 17 connecting means "between the respective valves and pistons are provided as the rods 18, 18.

Those portions of the chambers 16, 16 which are divided from the inlet chamber-13 by the pistons 17, 17 are provided with connections tojboth-the'i ltake space 13 and the outlet chamber 15 for the purpose of controlling the movement of the pistons 17, 17 v9 and in turn admitting water for flushing purposes from the inlet chamber 13 to the outlet chamber 15?.

These connections are of two types one for side or to'first one side andthen rapid succession.

' connection to the inlet 11,the valves15,15 are on their seats ,and the pistons 17, 17 are as I two adjustable control valves 20', 20 are provided. These valves may be in the form of adjustable screw valves as shown or constructed in any suitable manner.

The outlet ports from the chambers'16, 16', I have designated 21,21. 7 to a cylinder in which is located valves 22, 22. Each of these valves intheiorm 'illustrated, has a cut-away portion which is long enough to connect the port21 or. 2lwith anopening of a passage 23, 23" leading-to the outlet chamber 15*. The valves 22, '22 are: controlled bysprings 2 1', 2 1 which tend to force the valves to positions where the solid portion of the valve is in a place to interrupt'the passage of water between the chamber ports 21,

.21and the passages 23, 23: r

i "In axposition to operate either one of the valves 22, 225 is a lever 24: which is pivoted at"25';* .The levert24' is in a position to be easilyoperated and may be operated to either the 'otherin The operation'of my invention is as follows:

Letusassume the valves 20,20 to be respectively set to give small and large amounts of 7 water for flushing purposes. Undernormal 'condltions of use, the mlet chamber 13 18 under the static pressure ofthe water main shown in Figure 1. Assuming the operating lever 24 to be moved to the right, the opposite end will move to the left with a eon'sequent movement of the valve 22 toa point where the opening 21 will have communication with the passage 23"through"the cut away portion of the valve 22. As the full pressure of thewater main is-on the rear of the valve 15 and also on the exposed area of the cylinder 17, there willbe a resultant pressure tending toopen the valve'15 due to the l larger area of the cylinder.

This immediately causes the cylinder lti to lose its water con- ;tent as lthe cyli'nder 17jmoves to'foroe the water out through the opening'21 past the cutaway portion of the valve 22, and out through the passage 23 to the outlet chamber 15 which empties through the outlet open- -ing 12 to the closet.

As soon as the valve15leaves its seat there is: a streamof water deliveredto; the outlet chamber equal to the'c'apaci ty of'the valve 'openingllg "The sizes of the openings 21and passage 23 and thecut-away portion or the valve 22 are "such asto quickly openjthe valve'l'o" to its full opening-f *Vllhen the lever- 24:- is released, the

Thesepassages lead it is used. a V V s 1 While Ihaveillustrated and described in istic'is given the manual m'eansfl ,It isthus clear that the duration of the flushing operation determines the amount of 'water'" which is delivered. And since the amount o f'water passing the valve 20, determines the speed of closing of the valve 15, it is seen that the duration of the flushing operation will be determined by, the adjustment of the control valve 20.,

i Consequently after installation, it is necessary to adjust the control valves 20 and 20" until j ustthe proper amount of water is used in the two flushing operations controlled by these valves 20, 20,. Thus if the valve 20 is set to cause a rapid refilling of the cylinder 16 and the valve 20 is set for a slow refilling of the cylinder 16 it is clear that the valve 15' will control a small or shortfiush while the valve 15 will control a long flush delivering-a greater amount of water. 7 7 j It desirable to have even a greater amount of water than the settting of either valve 15 or 15' will cause alone, it is onlyfnecessaryt'o operate the two valves 22, 22 in rapid succes sion. The combined efiect of boththe small and the large flushing operations is then obtained; 1

amounts of water; Y

,Oneimpo'rtant advantage of myinvention is the ability to readily adjust the valves 20, -20. to obtain the exact amount of water for the particular type of installation with which detail one form of my invention, I desire to have it understood that I do no limit myself i to the exact disclosure andthat modifications and changes may be made without departing from the spiritof the invention and within the scope of the appended claims. 7 i i 1 Havingdescribed'my invention what I claim and desire to secure by Letters Patent 7 1.
